Some folks mentioned that their soldering skills were a bit limited and found the 161 little solder joints, needed to assemble the board, a bit daunting.
So, this is a pre-soldered & tested board with pre-programmed AVR microcontroller, MMJ socket, RF module, onboard Ds18B20 temperature sensor, 4 relays, terminal connectors for relays/inputs and PCB mounting hardware.
Also, an MMJ to RJ11 cable so it's all ready to plug into your reflashed Livebox.
